HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Corrects a problem in which /sbin/ddr_config does not accept values for
ReadyTimeSeconds larger than 255. The new limit is 86400 seconds (24 hours).
• Fixes problems with NUMA disk statistics.
• Fixes a KMF problem that can occur when some nodes in cluster are rebooted and
a device is shared by all the nodes.
• Changes the CAM subsystem message that is printed to the error log on a recovered
read error from "bad block number" to "block number."
• Adds per-binary big page controls to complement the system-wide tunable
attributes.
• Fixes how the NFS client handles full NFS version 3 64-bit fields.
• Corrects a potential security vulnerability where, under certain circumstances,
system integrity may be compromised. This may be in the form of improper file
or privilege management.
• Corrects a problem with hwmgr utility deletes while a SCSI scan is in progress.
• Improves scaling of IP reassembly code on large SMP machines. NFS servers are
especially susceptible when a large number of clients attempt to write at the same
time.
• Implements buffer cache page checksum caching for NFS client pages.
• Corrects a kernel memory fault caused by configuring a system to be a firewall
router without having the GWSCREEN subsystem built into the running kernel.
• Improves performance for applications with large in-core data sets.
• Corrects a problem in which the less than (<) and greater than () keys on the
Norwegian keyboard do not work in single-user mode.
• Adds the ability to join more than 20 IP multicast groups on a given socket.
• Changes the implementation of the NFS server's duplicate request cache from a
statically allocated monolithic entity to a dynamically allocated entity.
• Fixes a problem in which some IP fragments of NFS over UDP read replies may
be sent to the wrong MAC address.
• Improves the performance of systems that perform heavy file I/O.
• Provides an RFC3542 compliant implementation of IPv6 Advanced API.
• Provides support for latest version of bcm card.
• Updates Mobile IPv6 code to be compliant with the latest RFC.
• Fixes MIP6_CACHE_READ_TO_WRITE_LOCK() to not call lock_read_to_write()
when in lockmode=0 to avoid a panic.
• Corrects a problem with HSZ events that cause I/O errors rather than doing the
appropriate retries so the I/O can be successful.
• Adds read/write ability to XP control ports.
• Corrects a problem with a sensor error that can indicate a false over-temperature
condition on DS10/DS10L and TS10 systems.
• Fixes USB problems that prevent some USB keyboards and mice from working.
